If you ever want a unique point of view try a "fisheye" lens. Like
looking through a door peephole (which in fact is a "fisheye" type)
this order of lens sacrifices linear correction in favor of a very wide angle
of view. Originally made for creating "full sky" images when pointed
straight up, they had long ago been adopted by photographers for creation of
decidedly different points of view, and, today, even doing QuickTime movies
to display the interior of a condo or vacation home.

The Sigma Corporation is pleased to announce the launch of the new 4.5mm F2.8
EX DC Circular Fisheye HSM lens. Features include:

· The first 180 degree circular fisheye lens designed specifically for
APS-C size digital SLR cameras

· Fast F2.8 maximum aperture making it ideal for low light photography


· Minimum focusing distance of 13.5cm and a maximum magnification of 1:6


· SLD glass minimizes color aberration

· Equipped with HSM with full-time manual focus override

· Equisolid angle projection method is possible for art and scientific
use



This autofocus circular fisheye lens has an angle of view of 180 degrees in
all directions. It is exclusively designed for digital SLR cameras with the
APS-C size image sensor. When used in conjunction with digital SLRs with APS-C
size image sensors, it produces a circular image within the frame. The F2.8
large aperture value produces a bright image in the viewfinder and allows photographers
to take pictures in low light conditions, making it an ideal lens for Astrophotography
and Aurora photography. Due to the quantifiable angle/area relationship it produces,
this lens can be used for scientific and arts applications such as solid angle
measurements of cloud distribution over the sky or vegetation distribution of
the forest. The minimum focusing distance of 13.5cm/5.3inch and maximum magnification
of 1:6 make it particularly useful for close-up photography. SLD(Special Low
Dispersion)glass provides effective compensation of chromatic aberration. Sigma's
Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with
an inner focusing system that creates high definition and good image quality
over the whole frame. The HSM(Hyper Sonic Motor)ensures fast and quiet autofocusing
and allows full-time manual focus override by rotation of the focus ring.

The 50-150mm F2.8 APO EX DC OS HSM telephoto lens is the successor to the 50-150mm F2.8 APO EX DC II HSM. The updated lens now features Sigma’s own proprietary Optical Stabilizer (OS) technology, which offers the use of shutter speeds approximately four stops slower than would otherwise be possible. The lens design utilizes an inner-focusing and inner-zooming system that provides convenient handling and this, along with the OS feature, makes it favorable for high-performance, handheld, close-up photography. Additionally, the Hyper Sonic Motor (HSM) ensures quiet and high-speed auto focusing, while allowing full-time manual focus capability.

Sigma Corporation has announced the launch of the new 50-500 F4-6.3 EX DG/HSM lens. This high zoom ratio lens is optimized for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. This ultra-zoom lens employs a seven-group zoom system, which provides a high zoom magnification of 10x. Triple-cam Rear Focusing System ensures high precision throughout the whole focus range. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance. This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration. A zoom lock switch eliminates 'zoom creep' during transportation, a convenient addition when traveling. The HSM Hyper Sonic Motor models provide quiet high-speed AF function, as well as full-time manual focus capability., The rear focus mechanism produces a non-rotating front lens element which accepts a bayonet "Petal-type Hood", which prevents extraneous light from degrading the image quality. By adding an APO teleconverter (sold separately), you can use this lens as a 140-700mm f/7.3-8.8 MF ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 200-1000mm F10.4-12.6 MF ultra-telephoto zoom lens with a 2X teleconverter. Teleconverters can be used in 100mm – 500mm focal length range.
